The Solar Whiz SW-AU-R-40 is a solar-powered roof ventilator with market-leading performance rating. Ventilators like this one are used to flush out the heat that builds up in your roof space, increasing the heat load on your ceiling and making your home hot. It is common for roof spaces to get hotter than 70°C in summer which can be a serious problem for staying cool. Solar Whiz drags the hot air out of your house and introduces cooler outside air instead.

What is the Solar Whiz SW-AU-R-40?
The SW-AU-R-40 is the largest residential ventilator in our product range. It moves up to 2300m³/h, equivalent to around 23 conventional whirlybirds. The SW-AU-R-40 is perfect for roof ventilation and heat extraction for spaces up to or more than 250 square metres. Because the airflow capacity is so high these units can also be used in smaller commercial buildings.
Solar Whiz units are solar-powered. They are powerful and efficient ventilation solutions that deliver results without running costs or carbon emissions. You can choose to include thermostats and/or night operations kits that give you extra control over the unit. Thermostats can be fixed or adjustable, letting you control when the unit comes on and when it turns off. Night operations kits let you run the unit at night using mains power, but it also lets the unit ‘top-up’ on mains power during the day in low-light conditions.
The SW-AU-R-40 comes with:
- 40-Watt PV panel affixed to the fan cap,
- Flexible aluminium flashing for metal or tiled roofing,
- A 10-year warranty on the panel, and 2 on components for peace of mind.
